Collapse of a Bridge under Repair
Original language description
In 2008 a road bridge over an important railway was under essential repair. The composite concrete-steel bridge was partly pulled out to one side of the tracks and repaired. During the first steps of backward traction, the bridge suddenly slipped down from temporary supports on the railway. Incidentally at the same time the passing through intercity train crashed into the collapsed bridge at a high speed. The accident resulted in 8 fatalities, 63 injuries and considerable economic consequences. The additional damage of the bridge caused by the train and fast removal of wrecks significantly complicated forensic investigation concerning collapse causes. The background materials of the investigation were mostly limited to photographic documentation and few witnesses. A number of additional calculations did not reveal any prevailing cause of the collapse. Therefore, causal (Bayesian) network was used to identify the most significant causes including insufficient stiffness of temporary supports, their foundations and aerodynamic effects of high-speed trains passing under the bridge during a critical period before the collapse.
